Abstract An intraocular lens utilizing an optical portion and having at least one appendage with a first end portion connected to the optical portion. A second end portion of the appendage is intended for contacting the periphery of the eye. The terminus of the second end portion of the appendage includes a spacer which is positioned between the terminus of the appendage and the iris. An intermediate portion of the appendage connects the first and second end portions of the appendage.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
164 words
An intraocular lens for implantation in an eye comprising: a. a lens portion having an optical axis; and b. at least one appendage having a first end portion connected to said lens and extending outwardly therefrom, a second end portion including a terminus which is intended for contacting the periphery of the eye, said second end portion including a spacer for positioning between said terminus of said at least one appendage and the iris and positioned along said at least one appendage from said terminus toward said first end portion, said spacer comprising a solid mass being unitary with and extending from said terminus of said second end portion, said terminus and said spacer being free of openings therebetween, said spacer having a thickness extending transverse to said end portion and terminus in a direction parallel to said optical axis and terminating at a location spaced outwardly from said end portion and terminus and an intermediate portion connecting said first and second end portions.
Claim 2
Dependent Claim
164 words
An intraocular lens for implantation in an eye comprising: a. a lens portion having an optical axis; and b. at least one appendage having a first end portion connected to said lens and extending outwardly therefrom, a second end portion including a terminus which is intended for contacting the periphery of the eye, said second end portion including a spacer for positioning between said terminus of said at least one appendage and the iris and positioned along said at least one appendage from said terminus toward said first end portion, said spacer comprising a solid mass being unitary with and extending from said terminus of said second end portion, said terminus and said spacer being free of openings therebetween, said spacer having a thickness extending transverse to said end portion and terminus in a direction parallel to said optical axis and terminating at a location spaced outwardly from said end portion and terminus and an intermediate portion connecting said first and second end portions.
Claim 3
Dependent Claim
34 words
The intraocular lens of claim 1 which includes a pair of spacers connected to said second end portion of said at least one appendage, said pair of spacers being separated by a connecting member.
Claim 4
Dependent Claim
48 words
The intraocular lens of claim 1 in which said first end portion of said at least one appendage may be substantially in a first plane and the second end portion of said at least one appendage may lie substantially in a second plane which intersects said first plane.
Claim 5
Dependent Claim
15 words
The intraocular lens of claim 3 in which said intermediate portion includes an open loop.
Claim 6
Dependent Claim
33 words
The intraocular lens of claim 4 in which said intermediate portion lies partially in said first plane of said first end portion and partially in said second plane of said second end portion.
Claim 7
Dependent Claim
27 words
The intraocular lens of claim 3 in which said lens portion lies substantially in a third plane which intersects said first plane of said first end portion.
Claim 8
Dependent Claim
71 words
The intraocular lens of claim 1 which further comprises a second appendage having a first end portion connected to said lens portion and extruding outwardly therefrom, a second end portion which is intended for contracting the periphery of the eye, said second end portion including a spacer positioned between said terminus of said at least one appendage and the iris, and an intermediate portion connecting said first and second end portion.
